Description

Technical Field

[0001] This utility model belongs to the technical field of appearance inspection devices, specifically relating to a stator appearance visual intelligent inspection instrument. Background Technology

[0002] The stator is the core component of an electric motor, typically made of laminated silicon steel sheets and fixed inside the motor housing. Its main function is to generate a magnetic field or act as part of a magnetic field. In an electric motor, when current is passed through the stator windings, a rotating magnetic field is formed, driving the rotor to rotate. In a generator, the rotating rotor cuts the magnetic field of the stator windings, thereby generating current.

[0003] As a core component of a motor, the appearance quality of the stator directly affects the motor's performance and safety. However, traditional manual inspection has limitations such as low efficiency, fatigue, and insufficient accuracy. Therefore, it is necessary to use an intelligent visual inspection instrument. This equipment can quickly capture minute defects such as dents, scratches, and missing materials on the stator surface through a high-definition vision system and intelligent algorithms, achieving micron-level precision inspection. It can also process multiple types of defect identification and location in parallel, and simultaneously complete defect classification and data statistics. This not only greatly improves inspection efficiency (replacing manual labor to achieve 24-hour automated operation), but also avoids errors in human subjective judgment, providing accurate data support for quality control in motor manufacturing. It helps enterprises optimize production processes and reduce defect rates, making it an indispensable quality assurance device in modern automated motor production.

[0004] Existing stator appearance inspection equipment places the stator to be inspected directly on the inspection table. Since the stator has a columnar structure, it needs to be manually flipped over to be fully inspected, which affects the inspection efficiency and increases the workload of the inspection personnel. Utility Model Content

[0005] The purpose of this invention is to provide a stator appearance visual intelligent inspection instrument, which aims to solve the problem that existing stator appearance inspection equipment requires the stator to be inspected to be placed directly on the inspection table for inspection. Since the stator has a columnar structure, it needs to be manually flipped over for full inspection, which affects the inspection efficiency and increases the workload of the inspection personnel.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a stator appearance visual intelligent inspection instrument, comprising an instrument body, an inspection box mounted on the surface of the instrument body, a placement platform mounted on the surface of the inspection box, a first motor mounted in a rectangular groove on the surface of the placement platform, a fixed disk connected to the output end of the first motor, a second motor mounted in an adjustment groove on the inner wall of the placement platform, a trapezoidal lead screw connected to the output end of the second motor, a bearing mounted on the inner wall of the placement platform sleeved on the other side of the trapezoidal lead screw, a moving rod threadedly connected to the surface of the moving rod, a sliding rod slidably connected to the surface of a slide rod, the slide rod being connected to the adjustment groove on the inner wall of the placement platform, a limiting block connected to the surface of the moving rod, the limiting block being fitted into a through groove on the inner wall of a mounting base, a bearing mounted on the other side of the mounting base sleeved with a moving disk, and a control panel mounted on the surface of the placement platform.

[0007] As a preferred embodiment of the stator appearance visual intelligent inspection instrument of this utility model, the two ends of the moving rod are respectively provided with a circular threaded groove and a circular through groove, the shape and size of which are adapted to the trapezoidal lead screw and the slide rod.

[0008] As a preferred embodiment of the stator appearance visual intelligent inspection instrument of this utility model, the crossbar ends of the fixed disk and the moving disk are respectively annularly bonded with rubber pads.

[0009] As a preferred embodiment of the stator appearance visual intelligent inspection instrument of this utility model, the limiting block is a rectangular integrated structure, and the mounting base has a through groove on its surface, the shape and size of which are adapted to the moving rod and the limiting block.

[0010] In a preferred embodiment of the stator appearance visual intelligent inspection instrument of this utility model, the fixed disk and the movable disk are distributed in parallel on the surface of the placement table.

[0011] As a preferred embodiment of the stator appearance visual intelligent inspection instrument of this utility model, the first motor, the second motor, and the control panel form an electrical connection structure.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] The first motor installed on the placement platform rotates the stator, which is fitted between the fixed plate and the moving plate. This automatically fixes the position of the stator during appearance inspection while driving its rotation, so that the surface can be inspected from all angles without manual flipping, thereby improving inspection efficiency. At the same time, the position of the moving plate can be moved to clamp and fix stators of different sizes, thereby improving practicality and meeting the appearance inspection needs of different stator models.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figures 1-4This utility model provides the following technical solution: a stator appearance visual intelligent inspection instrument, including an inspection instrument body 1, an inspection box 2 mounted on the surface of the inspection instrument body 1, a placement platform 3 mounted on the surface of the inspection box 2, a first motor 4 mounted in a rectangular groove on the surface of the placement platform 3, a fixed plate 5 connected to the output end of the first motor 4, a second motor 6 mounted in an adjustment groove on the inner wall of the placement platform 3, a trapezoidal lead screw 7 connected to the output end of the second motor 6, a bearing mounted on the inner wall of the placement platform 3 on the other side of the trapezoidal lead screw 7, a moving rod 8 threadedly connected to the surface of the trapezoidal lead screw 7, and a sliding rod 9 slidably connected to the other side of the moving rod 8. The surface of the slide rod 9 is connected to the adjustment groove inside the inner wall of the placement platform 3. The surface of the moving rod 8 is connected to the limiting block 10. The surface of the limiting block 10 is fitted into the through groove inside the inner wall of the mounting base 11. The other side of the mounting base 11 is fitted with a bearing sleeve for the moving disk 12. The surface of the placement platform 3 is fitted with a control panel 13. In this design scheme, the detector body 1, the detection box 2 and the placement platform 3 constitute the main body of the visual inspection machine. The main body of the visual inspection machine contains a large number of related components. Since these are existing technologies and the core content of this technical solution is irrelevant to them, they will not be described in detail in this technical solution.

[0022] The main model of the vision inspection machine in this solution is: 3D vision inspection equipment.

[0023] In use: The main body of the vision inspection machine is equipped with dual placement platforms 3. The user first places the stator on the outer placement platform 3. After pressing the switch of the placement platform 3, the mechanical structure drives the two placement platforms 3 to exchange positions, so that the placement platform 3 with the stator is moved into the inspection station inside the equipment. The equipment uses 3D vision technology (such as through specific pattern projection, multi-view image acquisition, etc., combined with algorithms to accurately capture the appearance details of the stator) to inspect the appearance indicators such as surface defects (such as scratches, damage, etc.) and dimensional accuracy of the stator on the placement platform 3. At the same time, the other placement platform 3 is exchanged to the outside, so that the user can place the next stator to be inspected at the same time, realizing the continuous and efficient operation of the inspection process and completing the automated inspection and screening of the stator appearance quality.

[0024] Preferably, the moving rod 8 has a circular threaded groove and a circular through groove at both ends, and their shape and size are adapted to the trapezoidal lead screw 7 and the slide rod 9.

[0025] In practical use, the threaded groove and circular through groove on the surface of the movable rod 8 cause the movable rod 8, which is threadedly connected to the trapezoidal screw 7, to slide on the slide rod 9 away from the first motor 4 when the trapezoidal screw 7 rotates.

[0026] Preferably, rubber pads are circumferentially bonded to the ends of the crossbars on the surfaces of the fixed disk 5 and the movable disk 12.

[0027] In practical use, one side of the stator is fitted onto the crossbar on the surface of the fixed plate 5. The rubber pads attached to the crossbar of the fixed plate 5 increase the friction between the stator and the contact surface of the fixed plate 5, thereby fixing the position of the stator. The crossbar on the surface of the movable plate 12 is inserted into the other side of the stator. At the same time, the rubber pads attached to the crossbar of the movable plate 12 increase the friction between the contact surface of the movable plate 12 and the stator, so that it can be stably fitted onto the surface of the movable plate 12. Thus, the position of the stator is fixed by the cooperation of the fixed plate 5 and the movable plate 12, and it can rotate and display various angles on the surface of the placement platform 3 under the drive of the two.

[0028] Preferably, the limiting block 10 is a rectangular integral structure, and the mounting base 11 has a through groove on its surface, the shape and size of which are adapted to the moving rod 8 and the limiting block 10.

[0029] In practical use, the movable lever 8 is used.

[0030] Preferably, the fixed disk 5 and the movable disk 12 are distributed in parallel on the surface of the placement platform 3.

[0031] In practical use, by moving the position of the moving disk 12 in parallel, it can cooperate with the fixed disk 5 fixed on one side of the first motor 4 to insert and clamp the two sides of the stator.

[0032] Preferably, the first motor 4, the second motor 6, and the control panel 13 form an electrical connection structure.

[0033] In actual use, the start and stop of the first motor 4 and the second motor 6 can be controlled by the control buttons installed on the control panel 13. At the same time, the rotation direction of the second motor 6 can be controlled to adjust the position of the moving disk 12.

[0034] Working principle: During stator production, the appearance of the stator is inspected using the testing machine body 1. When inspecting the stator, the switch for the second motor 6 on the control panel 13 is pressed, causing its output end to rotate clockwise. This rotates the connected trapezoidal lead screw 7. As the lead screw 7 rotates, the threaded moving rod 8 on it is moved along the slide rod 9, sliding away from the first motor 4. This causes the moving disk 12 to move away from the fixed disk 5. The distance between the moving disk 12 and the fixed disk 5 is adjusted according to the model of the stator being inspected. Next, one side of the stator is fitted onto the crossbar on the surface of the fixed disk 5. The rubber pads attached to the crossbar of the fixed disk 5 increase the friction between the stator and the contact surface of the fixed disk 5, thereby fixing the position of the stator. At this time, the switch of the second motor 6 is turned on again, causing it to rotate counterclockwise, which drives the moving disk 12, which is away from the fixed disk 5, to move towards the fixed disk 5 until the crossbar on the surface of the moving disk 12 is inserted into the other side of the stator. At the same time, the rubber pads attached to the crossbar of the moving disk 12 increase the friction between the contact surface of the moving disk 12 and the stator, thus allowing it to be stably fitted. After the stator surface is inserted into the moving disk 12, the start switch of the moving disk 12 is turned off, and the electromagnetic controller installed on its surface locks the position of the trapezoidal lead screw 7, thereby fixing the position of the moving rod 8 on the trapezoidal lead screw 7. At the same time, the switch of the first motor 4 is turned on, which drives the connected fixed disk 5 and the moving disk 12, as well as the stator sleeved on it, to rotate on the bearing between the moving disk 12 and the mounting base 11, thereby rotating and displaying the clamped stator. Then, the switch on the detection box 2 is pressed, so that the placement platform 3, which is fixed on the outside of the stator, moves to the inner detection range. At the same time, the image acquisition component installed on the body 1 of the detector collects the appearance of the stator and analyzes and detects it. While the outer placement platform 3 moves to the inside, the other inner placement platform 3 moves to the outside at the same time. Then, the above operation is repeated to fix the position of another stator that needs to be detected, so that the stator can be automatically clamped and rotated at a constant speed during detection, so that the appearance can be inspected from all directions at one time, thereby improving the efficiency of appearance inspection.

[0035] Finally, it should be noted that the above are merely preferred embodiments of this utility model and are not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
